This invention relates to cone holders for use on knitting or other textile machines.

In knitting or other textile machines, where the yarn or thread is wound on cones, the latter will vary in length, degree of taper and diameter, with the result that the machines have to be adapted to the particular cone. It is, therefore, an object of this invention to provide a cone holder which will automatically adapt itself to various kinds and types of cones.

Another object of this invention is to provide a cone holder of this type which can be mounted on the present structure of creel frames.

A further object of this invention is to provide a cone holder which is of simple construction and will firmly hold a cone in operative position so that the cone can be easily and quickly applied or removed from the holder.

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing,

Figure 1 is a detailed side elevation of a cone holder constructed according to an embodiment of this invention, for mounting on the creel frame of a textile warping machine, showing a cone in vertical section mounted thereon, v

Figure 2 is a view similar to Figure 1, showing a different form of cone mounted on this holder,

Figure 3 is a sectional view taken on the line 33 of Figure 2,

Figure 4 is a plan view of the sliding or floating washer used with this device.

Referring to the drawing, the numeral Ill designates generally a portion of a creel frame for a knitting machine which has secured thereto a bolt II. The bolt I I, which may be either vertically or horizontally disposed, has mounted on the upper end thereof a washer I2 which is formed with downwardly flared inclined cone engaging fingers I3, which produce a threading means so that the cone will be locked by such fingers upon partial clockwise turning of the cone. The bolt I I has slidably thereon below the washer I2 2. second washer I4 which, as shown herein is formed with a rounded marginal edge IS. The lower washer I4 is a sliding or floating washer and is constantly urged upwardly by means of a spring I6 which engages about the bolt II' and bears at its lower end against the supporting portion of the creel frame with which the bolt I I is engaged. The upper end of the spring It bears against the lower side of the sliding or floating washer I4. Preferably the spring I6 is a relatively weak spring so that when a cone I I, as shown in Figure 1, is disposed in telescoping position over the washers I2 and I4, the lower or sliding washer I4 will move downwardly and auto-- matically adapt itself to the taper of the cone I! so that the lower washer I4 will engage the inside surface of the cone I1 at a point below the upper washer I2. The upper washer I2 is secured to the upper end of the bolt I I by means of a nut I8 which is threaded on a reduced stud I9 carried by the upper end of the bolt I I.

As shown in Figure 2, the \cone holder can easily and quickly adapt itself to different types of cones or cones having different tapers. The cone 20 shown in Figure 2, has a more shallow taper than the cone II shown in Figure 1, and in adapting itself to the cone 2n the floating or sliding washer I4 will be moved downwardly a greater distance until this washer I4 firmly contacts the inside surface of the cone 20 and coacts with the downwardly flared fingers of the washer I2 in providing spaced supporting surfaces for the cone. The washer I4 is substantially larger in diameter than the diameter of the washer I2 including the fingers I3 and is of such diameter with respect to the washer l2 that substantially all types of cones conventionally used with textile warping operations will be engaged by and supported in operative position by this holder.

In mounting the cone IT on the holder, the cone is extended over the washer I2 and the fingers I3 until the fingers I3 contact the inside surface of the cone. At this time the lower washer I4 is moved downwardly against the tension of spring I6. The cone I1 is then given a partial clockwise turn so that the fingers It will bite into the cone in a threading action and thereby lock the cone on the device. The cone is removed by counterclockwise turning thereof, followed by endwise movement.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim is:
